RELATED APPLICATIONS

This application claims benefit under 35 U.S.C. § 119(e) to U.S. Provisional Application Ser. No. 62/587,524 entitled “Selection of Time-Domain Resource Allocation Tables,” filed Nov. 17, 2017, the entire content of which is incorporated herein by reference.

TECHNICAL FIELD

Certain embodiments of the present disclosure relate, in general, to wireless communications and, more specifically, to the selection of time-domain resource allocation tables.

BACKGROUND

New Radio (NR) will support a bitfield in the downlink control information (DCI) to select the time-domain resource allocation for the physical uplink shared channel (PUSCH) and physical downlink shared channel (PDSCH) out of preconfigured entries in a table. Each entry in the table specifies a starting orthogonal frequency division multiplexing (OFDM) symbol and length in OFDM symbols of the allocation. Note that the starting OFDM symbol can be expressed either relative to the scheduling physical downlink control channel (PDCCH)/control channel resource set (CORESET) symbol(s) or in absolute OFDM symbol number within a slot or subframe.

SUMMARY

There currently exist certain challenge(s). Although, NR is very flexible, for example, in that NR supports different ways how to distribute system information and supports slot-based transmissions and non-slot-based transmissions, using a single time-domain resource allocation table is very limiting and can restrict scheduling in many cases. One possible solution would be to increase the resource allocation table size and by that enable more time-domain resource allocations. However, a drawback of that solution would be an increased downlink control information (DCI) size because more bits are needed to select an appropriate resource allocation.

Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. According to certain embodiments, a wireless device (e.g., user equipment, UE) is configured with multiple time-domain resource allocation tables. Which table to use is implicitly derived from other information available at both the network node (e.g., gNB) and the wireless device. Examples of this other information could be a Radio Network Temporary Identifier (RNTI), information contained in the DCI, which DCI format has been used for scheduling, which CORSET/search space has been used for scheduling, if the transmission is slot-based or non-slot-based, carrier aggregation related information, bandwidth part related information, slot format, and/or information indicating numerology (e.g., a cyclic prefix, an OFDM subcarrier spacing, etc.). According to certain embodiments, if the time-domain resource allocation is used in scheduling of system information (e.g., remaining minimum system information (RMSI)), the way system information is distributed (non-slot-based transmission vs. slot-based transmission) determines which table to use. According to certain embodiments, a wireless device configured with multiple time-domain resource allocation tables derives which table to use from information available at the wireless device and selects an entry out of that table based on an explicit bit field in the DCI that may be referred to as the time-domain resource allocation field.

According to certain embodiments a wireless device comprises memory and processing circuitry. The memory is operable to store instructions and the processing circuitry is operable to execute the instructions, whereby the wireless device is operable to determine one of a plurality of time-domain resource allocation tables based on first information received from a network node. Based on the determined one of the plurality of time-domain resource allocation table and second information received from the network node, the wireless device is operable to determine a time-domain resource allocated to the wireless device for transmission or reception of a wireless signal. The second information is different from the first information.

According to certain embodiments, a method performed by a wireless device comprises determining one of a plurality of time-domain resource allocation tables based on first information received from a network node.

Some of the embodiments contemplated herein will now be described more fully with reference to the accompanying drawings. Other embodiments, however, are contained within the scope of the subject matter disclosed herein, the disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art. Additional information may also be found in Appendix A and Appendix B.

FIG. 1 shows a wireless device configured with multiple (in the example, two) time-domain resource allocation tables. Examples of time-domain resource allocation tables include pre-defined tables with default values for the time domain resource allocation, tables configured using RRC signaling, and a combination of pre-defined and RRC-configured tables. The time-domain resource allocation tables indicate an allocation of time-domain resources, such as time-domain resources of the PUSCH or PDSCH, for transmission or reception of a wireless signal. In some embodiments, the time-domain resource allocation tables indicate the allocation of time-domain resources with reference to OFDM symbols. For example, FIG. 1 shows that the time-domain resource allocation tables comprise different combinations of starting OFDM symbol position and duration in OFDM symbols for the time-domain resource allocation. As can be seen, the time-domain resource allocation tables include multiple entries, and the different table entries may differ in at least one of OFDM starting symbol and/or scheduled time duration in OFDM symbols. The OFDM symbols may be indicated using any two parameters selected from start symbol, stop symbol, and duration in symbols (e.g., start symbol and stop symbol, start symbol and duration, or stop symbol and duration). The start symbol can be absolute with respect to the slot boundary, or relative to a scheduling DCI/CORESET. Different tables could also have different definitions with respect to the starting (or ending) OFDM symbol. For example, some tables could express the starting (or ending) OFDM symbol in absolute OFDM symbol number of a slot while other tables would express the starting (or ending) symbol relative to PDCCH/CORESET symbol(s) used to schedule PDSCH/PUSCH. The absolute numbering could be useful for slot-based or Type A transmission while relative numbering could be preferred by non-slot-based or Type B transmission. In principle, different tables could have different number of entries; however, in the examples shown in FIG. 1 , the same number of entries in each table is assumed.

The wireless device determines which time-domain resource allocation table to use based on first information received from a network node, such as a base station. The wireless device determines a time-domain resource allocated to the wireless device based on the time-domain resource allocation table determined from the first information and based on second information received from the network node. The second information is different from the first information. In some embodiments, the second information indicates which entry of the determined table to use to determine the time-domain resource allocated to the wireless device. For example, the second information may comprise a time-domain resource allocation field, such as a bit field, received in DCI. With respect to the example illustrated in FIG. 1 , each table includes four entries such that a time-domain resource allocation field comprising a two bits-wide bit field may be used to select one of the four entries in the table (e.g., value “00” to select the first entry, “01” to select the second entry, “10” to select the third entry, and “11” to select the fourth entry).

As described above, the wireless device determines the table based on first information. The first information comprises information other than the time-domain resource allocation field received in the DCI. Examples of this other information could be a Radio Network Temporary Identifier (RNTI), information contained in the DCI, which DCI format has been used for scheduling, which CORSET/search space has been used for scheduling, if the transmission is slot-based or non-slot-based, carrier aggregation related information, bandwidth part related information, slot format, and/or information indicating numerology (e.g., a cyclic prefix, an OFDM subcarrier spacing, etc.), as further described below.

In some embodiments, the first information could be another field in the DCI (i.e., a field other than the time-domain resource allocation field) that is already being signaled for another purpose. For example, if DCI includes a bit to differentiate Type A scheduling and Type B scheduling, this bit can be used to select one of the two tables in FIG. 1 . Another example could be a bit that differentiates slot-based transmissions and non-slot-based transmission. Slot B scheduling, non-slot-based transmissions, and mini-slots are transmissions which duration is typically short. Slot-based transmissions typically have transmission lengths in the order of a slot. Therefore, it makes sense to use two different time-domain resource allocation tables based on a Type A/Type B or non-slot-based-transmission/slot-based-transmission differentiator bit.

If multi-slot scheduling is dynamically indicated in the DCI using a multi-slot indicator bit, this bit can be used as the first information to differentiate a time-domain resource allocation table to be used for single slot and multi-slot (slot aggregation) transmission. In these two cases resource allocations are obviously different. A multi-slot time-domain resource allocation can - in addition to the symbol information - also contain slot information. Here the time-domain resource allocation field received in DCI could be larger bit field if the multi-slot indicator bit is set to enable more time-domain resource allocations. The same principle applies if multi-slot scheduling is not indicated via a multi-slot indicator bit in the DCI but in any other way.

Certain embodiments of the present disclosure use the DCI format (e.g., regular DCI or fallback DCI) as the first information for selecting a time-domain resource allocation table. For example, for NR, it has been discussed in 3GPP to use two different DCI variants. The first variant is a regular DCI which can be used for all kinds of signaling or configuring needed. This regular DCI varies in size and format depending on the its use (i.e., depending on the actual RRC configuration), somewhat similar to LTE DCI formats. The second variant is a fallback DCI with a fixed and predefined size. The fixed-size fallback DCI is typically needed during RRC reconfigurations, when there may be a period of configuration uncertainty during which it is valuable to have a fixed sized DCI known to both the network and the UE, to limit the effect of the configuration uncertainty for the wireless communication. The problem of configuration uncertainty occurs when the network does not know when the UE applies the RRC reconfiguration. For example, the UE may have to list the information, or there may be multiple retransmissions needed before the RRC command reaches the UE. Hence there is a period when the UE may have applied the new configuration, but the network is not aware of it, or vice versa. During this period there is thus a need for a way to communicate which is “always” known by both sides and, and this need is fulfilled by using the fallback DCI that is not configurable.

A wireless device can be configured with multiple control channel resource sets (CORESETS) and each CORESET can contain one or more search spaces. The CORESET and/or search space that has been used to schedule the transmission can be used as the first information for determining the time-domain resource allocation table.

A DCI contains a downlink/uplink (DL/UL) indicator bit that indicates if the transmission is DL or UL. Due to the difference in frame structure and different processing times between DL assignment reception → DL data reception and UL grant reception →UL data transmission, it is likely that DL and UL require different time-domain resource allocations. Therefore, the DL/UL indicator bit can be used as the first information for determining the time-domain resource allocation table.

In case of carrier aggregation, a wireless device is configured with multiple carriers. Different carriers might have different numerologies, and different need to coexist with long term evolution (LTE), and are set up with different DL/UL configurations. Then it makes sense to support different time-domain resource allocations for different carriers. Therefore, depending on the scheduled carrier, a time-domain resource allocation table is selected (i.e.., the scheduled carrier may be used as first information for determining the time-domain resource allocation table). If no cross-carrier scheduling is applied (i.e., PDCCH is transmitted on same carrier as PDSCH or on associated carrier to PUSCH carrier) the carrier on which the scheduling DCI is transmitted determines the time-domain resource allocation table. If cross carrier scheduling is used (i.e., PDCCH is transmitted on another carrier as PDSCH or associated carrier to PUSCH carrier), information in the DCI or how the DCI is transmitted indicates the PDSCH/PUSCH carrier. For example, a Carrier Indicator Field (CIF) can be included in the DCI pointing to the PDSCH/PUSCH carrier. Different offsets with respect to how a search space is located in a CORESET might also be used to indicate the PDSCH/PUSCH carrier. Based on the identified carrier, a time-domain resource allocation table is selected.

In LTE and NR, transmissions can be scheduled using different Radio Network Temporary Identifiers (RNTI). As the name implies, RNTI is a kind of identification number, used to identify a specific radio channel and sometimes also a specific UE. Some examples are:

-   C-RNTI: used for scheduling at cell level. C-RNTI is a unique UE id     used as an identifier of the RRC Connection and for scheduling. -   RA-RNTI used during random access procedure. -   SI-RNTI: identification of System Information in the downlink. -   P-RNTI: identification of Paging and System Information change     notification in the downlink.

For example, it could be envisioned that different RNTIs are used to schedule slot-based transmission and non-slot-based transmissions. Different RNTIs can therefore be mapped to different time-domain resource allocation and the wireless device- depending on which RNTI it detects - selects a time-domain resource allocation table. Thus, an RNTI may be used as first information for determining the time-domain resource allocation table.

NR supports different numerologies, e.g., OFDM subcarrier spacing and/or cyclic prefix. Different numerologies (including cyclic prefix) can be used to optimize transmissions with respect to latency or individually adopt the numerology to the current radio conditions of a terminal. Different numerologies can be mapped to different time-domain resource allocation and the wireless device, based on the numerology of a transmission, selects the correct time-domain resource allocation table. In NR, different bandwidth parts (BWP) will be used for different numerologies. Different BWP might thus use different time-domain resource allocation tables. For example, If the DCI contains a BWP indicator field this can be used as first information for determining the time-domain resource allocation table.

Yet another possibility is to use the slot format as first information for determining the time-domain resource allocation table. For example, the wireless device can determine which table to use based on a slot format determined by the wireless device. The slot format can be determined based on the slot in which PDSCH is received (or PUSCH is transmitted). Alternately the slot format can be determined based on the format applicable to the first slot from which the PDSCH is received (or PUSCH is transmitted) in case of multi-slot transmissions. The slot format can be determined by the wireless device via higher layer signaling and/or L1 signaling (e.g., slot format indicator received in DCI or group-common PDCCH) and indicates at least one more of downlink/uplink/unknown symbols within a slot.

In initial access, Remaining Minimum System Information (RMSI) can be transmitted based on slot-based transmissions and non-slot-based transmissions. The Master Information Block (MIB) on the Physical Broadcast Channel (PBCH) contain information about how RMSI is distributed. Depending on how RMSI is transmitted, different time-domain resource allocation tables can be used to maximize scheduling flexibility for RMSI. Thus, information related to how the RMSI is transmitted may be used as first information for determining the time domain resource allocation table.

FIG. 2 shows a flow chart of a method in a wireless device for how to select a time-domain resource allocation table and a time-domain resource allocation entry within the table. First, the method comprises selecting a time-domain resource allocation table. In some embodiments, the method comprises selecting one of multiple time-domain resource allocation tables based on information available to the network node and the wireless device, for example, without the network node having to send DCI explicitly indicating which time-domain resource allocation table the wireless device should select. Second, the method comprises determining a time-domain resource allocation entry within the selected table. For example, from the network node perspective, the network node determines the time-domain resource allocation entry and explicitly signals the entry in the time-domain resource allocation field in DCI. From the wireless device perspective, the wireless device determines the time-domain resource allocation entry within the selected table based on the time-domain resource allocation field received in DCI from the network node.

In addition, it is possible that the tables discussed above are configured from a set of possible time-domain resource allocations. An example of a collection of time-domain resource allocations is given below in Table 1.

TABLE 1 Possible time-domain resource allocations (captured in spec) Time domain RA Index (I_TDRA) PDSCH start offset from last OFDM symbol of PDCCH (X syms) PDSCH length (L1 syms) Applicable slots (L2 slots) Comments 0-13 0 1-14 1 1^(st) index corresponds to L1=1; 2^(nd) index to L1=2, ... 14-24 1 1-13 1 “ 25-36 2 1-12 1 “ 37-48 3 1-11 1 “ 49-59 4 1-10 1 60-72 -1 3-14 1 “ 73-84 -2 4-14 1 “ 85-91 0 14 2-8 1^(st) index corresponds to L2=1; 2^(nd) index to L2=2, ... 92-98 0 13 2-8 “ 99-105 0 12 2-8 “ 106-112 0 11 2-8 “ 113-119 1 13 2-8 “ 120-126 1 12 2-8 “ 127-133 1 11 2-8 “ 134-140 2 12 2-8 “ 141-147 2 11 2-8 “ 148-155 3 11 2-8 “ 156-163 All DL symbols determined from the SFI of the slot in which PDSCH is received 1-8 “ 164 All DL symbols determined from the SFI of the slot in which PDSCH is received; starting from the last OFDM symbol in which PDCCH is received 1 other values reserved (e.g., up to 255)

In Table 1, the multi-slot scheduling has been directly included as a separate column in the table. It is found under the column “Applicable slots (L2 slots).” In other embodiments, the multi-slot scheduling may be indicated by other means. In some embodiments, four entries of Table 1 could be configured to build Table A of FIG. 1 (e.g., Table A has four entries in the example shown in FIG. 1 ). The signaling for this can be in system information or by wireless device-specific signaling by radio resource control (RRC). Similar methods can also be done for Table B and so on.

A table would then be selected according first information, such as an RNTI, information contained in the DCI, which DCI format has been used for scheduling, which CORSET/search space has been used for scheduling, if the transmission is slot-based or non-slot-based, carrier aggregation related information, bandwidth part related information, slot format, and/or information indicating numerology (e.g., a cyclic prefix, an OFDM subcarrier spacing, etc.). The time-domain resource allocation field in the DCI will point out an entry in the selected table. It is further observed that although Table 1 is described for PDSCH, a similar table can be constructed for PUSCH. As said earlier, different tables (Table A, Table B, ...) can be configured for different CORESET/search spaces/..., and each Table A, B, ... is configured with rows from Table 1.

Specific for initial access, some entries for Table 1 can be directly hardcoded in the specification for scheduling of example system information, paging, random access response, Message 3 in the random access procedure. If there would be no default values, additional signaling would be needed in MIB/PBCH to configure the default time-domain resource allocation(s). These values can also be default values the wireless device uses unless configured with a new time-domain resource allocation table.

FIG. 3 depicts a method in accordance with particular embodiments. In certain embodiments, the method may be performed by a wireless device, such as a UE. The method begins at step 30 with determining one of a plurality of time-domain resource allocation tables based on first information received from a network node. The method continues to step 32 with determining a time-domain resource allocated to the wireless device for transmission or reception of a wireless signal based on the determined one of the plurality of time-domain resource allocation tables and second information received from the network node different from the first information. Examples of first information, i.e., information from which the wireless device may determine the time-domain resource allocation table and second information, i.e., information from which the wireless device may determine the time-domain resource include, but are not limited to, the examples described with respect to FIGS. 1-2 and above and the Group A embodiments below. In some embodiments, the method further comprises transmitting or receiving the wireless signal at step 34 using the determined time-domain resource.

FIG. 4 depicts a method in accordance with particular embodiments. In certain embodiments, the method may be performed by a network node, such as a base station. The method begins at step 40 with determining a time-domain resource to allocate to a wireless device for transmission or reception of a wireless signal. For example, in some embodiments, the network node determines the time-domain resource allocation based on an identified table and other information, such as current scheduling needs. The network node may then select the entry from the table that corresponds to the determined time-domain resource allocation. Additionally, the network node may determine second information for indicating the selected entry to the wireless device. The method proceeds to step 42 with sending the wireless device first information from which the wireless device determines one of a plurality of time-domain resource allocation tables and second information from which the wireless device determines the time-domain resource based on the determined one of the plurality of time-domain resource allocation tables. The second information is different from the first information. Examples of first information, i.e., information sent to the wireless device from which the wireless device may determine the time-domain resource allocation table and second information, i.e., information sent to the wireless device from which the wireless device may determine the time-domain resource include, but are not limited to, the examples described with respect to FIGS. 1-2 and above and the Group B embodiments below.

FIG. 5 illustrates a schematic block diagram of an apparatus 50 in a wireless network (for example, the wireless network shown in FIG. 6 ). The apparatus may be implemented in a wireless device or network node (e.g., wireless device 110 or network node 160 shown in FIG. 6 ). Apparatus 50 is operable to carry out the example method described with reference to FIG. 3 or FIG. 4 and possibly any other processes or methods disclosed herein. It is also to be understood that the method of FIGS. 3 and 4 are not necessarily carried out solely by apparatus 50. At least some operations of the method can be performed by one or more other entities.

Virtual Apparatus 50 may comprise processing circuitry, which may include one or more microprocessor or microcontrollers, as well as other digital hardware, which may include digital signal processors (DSPs), special-purpose digital logic, and the like. The processing circuitry may be configured to execute program code stored in memory, which may include one or several types of memory such as read-only memory (ROM), random-access memory, cache memory, flash memory devices, optical storage devices, etc. Program code stored in memory includes program instructions for executing one or more telecommunications and/or data communications protocols as well as instructions for carrying out one or more of the techniques described herein, in several embodiments. In some implementations, the processing circuitry may be used to cause configuration information unit 52, time resource determination unit 54, communication unit 56, and any other suitable units of apparatus 50 to perform corresponding functions according one or more embodiments of the present disclosure.

As illustrated in FIG. 5 , apparatus 50 includes configuration information unit 52, time resource determination unit 54, and communication unit 56. In certain embodiments, configuration information unit 52 is configured to determine first information and second information. For example, when used in a network node, configuration information unit 52 determines first information to send to a wireless device from which the wireless device determines one of a plurality of tables, and second information from which the wireless determines (based on the one of the plurality of tables determined from the first information) an allocated time-domain resource. When used in a wireless device, configuration information unit 52 determines the first and second information received from the network node. Time resource determination unit 54 determines a time resource allocated to the wireless device for transmission or reception of a wireless signal. When used in a network node, time resource determination unit 54 may allocate a time-domain resource and may indicate the allocated time-domain resource to the network node’s configuration information unit 52 so that the configuration information unit 52 can determine the first and second information to send the wireless device (e.g., first and second information that corresponds to the allocated time-domain resource). When used in a wireless device, time resource determination unit 54 can receive the first and second information from the network node (e.g., via the wireless device’s configuration information module 52) and can use the first and second information to determine the time-domain resource that the network node has allocated for the transmission or reception of a wireless signal. Communication unit 56 transmits or receives the wireless signal according to the allocated time domain resource that was determined by the time resource determination unit 54.

The term unit may have conventional meaning in the field of electronics, electrical devices and/or electronic devices and may include, for example, electrical and/or electronic circuitry, devices, modules, processors, memories, logic solid state and/or discrete devices, computer programs or instructions for carrying out respective tasks, procedures, computations, outputs, and/or displaying functions, and so on, as such as those that are described herein.

In some embodiments a computer program, computer program product or computer readable storage medium comprises instructions which when executed on a computer perform any of the embodiments disclosed herein. In further examples the instructions are carried on a signal or carrier and which are executable on a computer wherein when executed perform any of the embodiments disclosed herein.

Although the subject matter described herein may be implemented in any appropriate type of system using any suitable components, the embodiments disclosed herein are described in relation to a wireless network, such as the example wireless network illustrated in FIG. 6 . For simplicity, the wireless network of FIG. 6 only depicts network 106, network nodes 160 and 160 b, and WDs 110, 110 b, and 110 c. In practice, a wireless network may further include any additional elements suitable to support communication between wireless devices or between a wireless device and another communication device, such as a landline telephone, a service provider, or any other network node or end device. Of the illustrated components, network node 160 and wireless device (WD) 110 are depicted with additional detail. The wireless network may provide communication and other types of services to one or more wireless devices to facilitate the wireless devices’ access to and/or use of the services provided by, or via, the wireless network.

The wireless network may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. In some embodiments, the wireless network may be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards.

Network 106 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), packet data networks, optical networks, wide-area networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices.

Network node 160 and WD 110 comprise various components described in more detail below. These components work together in order to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections.

As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. Examples of network nodes include, but are not limited to, access points (APs) (e.g., radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&M nodes, OSS nodes, SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network.

In FIG. 6 , network node 160 includes processing circuitry 170, device readable medium 180, interface 190, auxiliary equipment 184, power source 186, power circuitry 187, and antenna 162. Although network node 160 illustrated in the example wireless network of FIG. 6 may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node 160 are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium 180 may comprise multiple separate hard drives as well as multiple RAM modules).

Similarly, network node 160 may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node 160 comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB’s. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. In some embodiments, network node 160 may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium 180 for the different RATs) and some components may be reused (e.g., the same antenna 162 may be shared by the RATs). Network node 160 may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node 160, such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node 160.

Processing circuitry 170 is configured to perform any determining, calculating, or similar operations (e.g., certain obtaining operations) described herein as being provided by a network node. These operations performed by processing circuitry 170 may include processing information obtained by processing circuitry 170 by, for example, converting the obtained information into other information, comparing the obtained information or converted information to information stored in the network node, and/or performing one or more operations based on the obtained information or converted information, and as a result of said processing making a determination.

Processing circuitry 170 may comprise a combination of one or more of a microprocessor, controller, microcontroller, central processing unit, digital signal processor, application-specific integrated circuit, field programmable gate array, or any other suitable computing device, resource, or combination of hardware, software and/or encoded logic operable to provide, either alone or in conjunction with other network node 160 components, such as device readable medium 180, network node 160 functionality. For example, processing circuitry 170 may execute instructions stored in device readable medium 180 or in memory within processing circuitry 170. Such functionality may include providing any of the various wireless features, functions, or benefits discussed herein. In some embodiments, processing circuitry 170 may include a system on a chip (SOC).

In some embodiments, processing circuitry 170 may include one or more of radio frequency (RF) transceiver circuitry 172 and baseband processing circuitry 174. In some embodiments, radio frequency (RF) transceiver circuitry 172 and baseband processing circuitry 174 may be on separate chips (or sets of chips), boards, or units, such as radio units and digital units. In alternative embodiments, part or all of RF transceiver circuitry 172 and baseband processing circuitry 174 may be on the same chip or set of chips, boards, or units

In certain embodiments, some or all of the functionality described herein as being provided by a network node, base station, eNB or other such network device may be performed by processing circuitry 170 executing instructions stored on device readable medium 180 or memory within processing circuitry 170. In alternative embodiments, some or all of the functionality may be provided by processing circuitry 170 without executing instructions stored on a separate or discrete device readable medium, such as in a hard-wired manner. In any of those embodiments, whether executing instructions stored on a device readable storage medium or not, processing circuitry 170 can be configured to perform the described functionality. The benefits provided by such functionality are not limited to processing circuitry 170 alone or to other components of network node 160, but are enjoyed by network node 160 as a whole, and/or by end users and the wireless network generally.

Device readable medium 180 may comprise any form of volatile or non-volatile computer readable memory including, without limitation, persistent storage, solid-state memory, remotely mounted memory, magnetic media, optical media, random access memory (RAM), read-only memory (ROM), mass storage media (for example, a hard disk), removable storage media (for example, a flash drive, a Compact Disk (CD) or a Digital Video Disk (DVD)), and/or any other volatile or non-volatile, non-transitory device readable and/or computer-executable memory devices that store information, data, and/or instructions that may be used by processing circuitry 170. Device readable medium 180 may store any suitable instructions, data or information, including a computer program, software, an application including one or more of logic, rules, code, tables, etc. and/or other instructions capable of being executed by processing circuitry 170 and, utilized by network node 160.

As illustrated, interface 190 comprises port(s)/terminal(s) 194 to send and receive data, for example to and from network 106 over a wired connection. Interface 190 also includes radio front end circuitry 192 that may be coupled to, or in certain embodiments a part of, antenna 162. Radio front end circuitry 192 comprises filters 198 and amplifiers 196. Radio front end circuitry 192 may be connected to antenna 162 and processing circuitry 170. Radio front end circuitry may be configured to condition signals communicated between antenna 162 and processing circuitry 170. Radio front end circuitry 192 may receive digital data that is to be sent out to other network nodes or WDs via a wireless connection. Radio front end circuitry 192 may convert the digital data into a radio signal having the appropriate channel and bandwidth parameters using a combination of filters 198 and/or amplifiers 196. The radio signal may then be transmitted via antenna 162. Similarly, when receiving data, antenna 162 may collect radio signals which are then converted into digital data by radio front end circuitry 192. The digital data may be passed to processing circuitry 170. In other embodiments, the interface may comprise different components and/or different combinations of components.

In certain alternative embodiments, network node 160 may not include separate radio front end circuitry 192, instead, processing circuitry 170 may comprise radio front end circuitry and may be connected to antenna 162 without separate radio front end circuitry 192. Similarly, in some embodiments, all or some of RF transceiver circuitry 172 may be considered a part of interface 190. In still other embodiments, interface 190 may include one or more ports or terminals 194, radio front end circuitry 192, and RF transceiver circuitry 172, as part of a radio unit (not shown), and interface 190 may communicate with baseband processing circuitry 174, which is part of a digital unit (not shown).

Antenna 162 may include one or more antennas, or antenna arrays, configured to send and/or receive wireless signals. Antenna 162 may be coupled to radio front end circuitry 190 and may be any type of antenna capable of transmitting and receiving data and/or signals wirelessly. In some embodiments, antenna 162 may comprise one or more omni-directional, sector or panel antennas operable to transmit/receive radio signals between, for example, 2 GHz and 66 GHz. An omni-directional antenna may be used to transmit/receive radio signals in any direction, a sector antenna may be used to transmit/receive radio signals from devices within a particular area, and a panel antenna may be a line of sight antenna used to transmit/receive radio signals in a relatively straight line. In some instances, the use of more than one antenna may be referred to as MIMO. In certain embodiments, antenna 162 may be separate from network node 160 and may be connectable to network node 160 through an interface or port.

Antenna 162, interface 190, and/or processing circuitry 170 may be configured to perform any receiving operations and/or certain obtaining operations described herein as being performed by a network node. Any information, data and/or signals may be received from a wireless device, another network node and/or any other network equipment. Similarly, antenna 162, interface 190, and/or processing circuitry 170 may be configured to perform any transmitting operations described herein as being performed by a network node. Any information, data and/or signals may be transmitted to a wireless device, another network node and/or any other network equipment.

Power circuitry 187 may comprise, or be coupled to, power management circuitry and is configured to supply the components of network node 160 with power for performing the functionality described herein. Power circuitry 187 may receive power from power source 186. Power source 186 and/or power circuitry 187 may be configured to provide power to the various components of network node 160 in a form suitable for the respective components (e.g., at a voltage and current level needed for each respective component). Power source 186 may either be included in, or external to, power circuitry 187 and/or network node 160. For example, network node 160 may be connectable to an external power source (e.g., an electricity outlet) via an input circuitry or interface such as an electrical cable, whereby the external power source supplies power to power circuitry 187. As a further example, power source 186 may comprise a source of power in the form of a battery or battery pack which is connected to, or integrated in, power circuitry 187. The battery may provide backup power should the external power source fail. Other types of power sources, such as photovoltaic devices, may also be used.

Alternative embodiments of network node 160 may include additional components beyond those shown in FIG. 6 that may be responsible for providing certain aspects of the network node’s functionality, including any of the functionality described herein and/or any functionality necessary to support the subject matter described herein. For example, network node 160 may include user interface equipment to allow input of information into network node 160 and to allow output of information from network node 160. This may allow a user to perform diagnostic, maintenance, repair, and other administrative functions for network node 160.

As used herein, wireless device (WD) refers to a device capable, configured, arranged and/or operable to communicate wirelessly with network nodes and/or other wireless devices. Unless otherwise noted, the term WD may be used interchangeably herein with user equipment (UE). Communicating wirelessly may involve transmitting and/or receiving wireless signals using electromagnetic waves, radio waves, infrared waves, and/or other types of signals suitable for conveying information through air. In some embodiments, a WD may be configured to transmit and/or receive information without direct human interaction. For instance, a WD may be designed to transmit information to a network on a predetermined schedule, when triggered by an internal or external event, or in response to requests from the network. Examples of a WD include, but are not limited to, a smart phone, a mobile phone, a cell phone, a voice over IP (VoIP) phone, a wireless local loop phone, a desktop computer, a personal digital assistant (PDA), a wireless cameras, a gaming console or device, a music storage device, a playback appliance, a wearable terminal device, a wireless endpoint, a mobile station, a tablet, a laptop, a laptop-embedded equipment (LEE), a laptop-mounted equipment (LME), a smart device, a wireless customer-premise equipment (CPE). a vehicle-mounted wireless terminal device, etc.. A WD may support device-to-device (D2D) communication, for example by implementing a 3GPP standard for sidelink communication, vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-everything (V2X) and may in this case be referred to as a D2D communication device. As yet another specific example, in an Internet of Things (IoT) scenario, a WD may represent a machine or other device that performs monitoring and/or measurements, and transmits the results of such monitoring and/or measurements to another WD and/or a network node. The WD may in this case be a machine-to-machine (M2M) device, which may in a 3GPP context be referred to as an MTC device. As one particular example, the WD may be a UE implementing the 3GPP narrow band internet of things (NB-IoT) standard. Particular examples of such machines or devices are sensors, metering devices such as power meters, industrial machinery, or home or personal appliances (e.g., refrigerators, televisions, etc.) personal wearables (e.g., watches, fitness trackers, etc.). In other scenarios, a WD may represent a vehicle or other equipment that is capable of monitoring and/or reporting on its operational status or other functions associated with its operation. A WD as described above may represent the endpoint of a wireless connection, in which case the device may be referred to as a wireless terminal. Furthermore, a WD as described above may be mobile, in which case it may also be referred to as a mobile device or a mobile terminal.

The type of interaction may vary depending on the type of user interface equipment 132 installed in WD 110. For example, if WD 110 is a smart phone, the interaction may be via a touch screen; if WD 110 is a smart meter, the interaction may be through a screen that provides usage (e.g., the number of gallons used) or a speaker that provides an audible alert (e.g., if smoke is detected).

An article of manufacture, such as one utilizing a communication system may be tangibly embodied in storage medium 221, which may comprise a device readable medium.

In FIG. 7 , processing circuitry 201 may be configured to communicate with network 243 b using communication subsystem 231. Network 243 a and network 243 b may be the same network or networks or different network or networks.

APPENDIX A

Hereinafter, further example embodiments related to NR resource allocation design issues are discussed, and more specifically time domain resource allocation.

Time Allocation

In 3GPP RAN1#90bis meeting the following was agreed:

-   Agreements:     -   For both slot and mini-slot, the scheduling DCI can provide an         index into a UE-specific table giving the OFDM symbols used for         the PDSCH (or PUSCH) transmission         -   starting OFDM symbol and length in OFDM symbols of the             allocation         -   For Further Study (FFS): one or more tables         -   FFS: including the slots used in case of             multi-slot/multi-mini-slot scheduling or slot index for             cross-slot scheduling         -   FFS: May need to revisit if SFI support non-contiguous             allocations     -   At least for RMSI scheduling         -   At least one table entry needs to be fixed in the spec -   Regarding whether one or more tables should be specified, it is     believed that multiple tables can provide more flexibility in     scheduling. However, in order to limit the DCI message size to     select the tables, the number of tables may be limited to two. The     table entries in the two tables can differ in starting OFDM symbol     and/or duration. The selection of tables can be based on other     fields in DCI message such as whether Type A or Type B scheduling is     used, or a field that signals whether slot-based or mini-slot based     transmission is scheduled.

Proposal 3-1: To provide more flexibility in time domain resource allocation, two tables are specified with different starting OFDM symbol and duration in OFDM symbols.

For NR, data transmission may occupy (almost) all OFDM symbols in a slot or, in case of a mini-slot transmission, only some of them. These possibilities can be handled in a unified way by including information in the DCI about the PUSCH and PDSCH the starting and ending position. To limit the DCI overhead while at the same time provide some flexibility one possibility is to have, e.g., 3 bits in the DCI pointing into different combinations of starting and ending positions.

The combinations should also be aligned with OFDM symbol positions given by SFI (slot format indicator) in group common PDCCH (e.g., the combinations shown in [1]). For DL, the reference for starting and ending positions should be with respect to the first OFDM symbol of the PDCCH carrying the corresponding DCI. Some starting positions may be -ve values to accommodate the cases where PDSCH starts before the symbol in which PDCCH coreset is configured. To limit UE buffering requirements, only limited -ve values should be allowed (e.g., only -2, -1).

Data may also span multiple slots in case of slot aggregation/repetition. To handle slot aggregation, the UE assumes the same time resource allocation in slots wherein the transmission is repeated.

Proposal 3-2: When slot aggregation/repetition is applied, the UE assumes the same time resource allocation in slots wherein the transmission is repeated.

To have more efficiency in DCI message it would be possible to make the bit fields in the DCI message depending on which CORESET the DCI is transmitted from. This is to allow more appropriate options of configurations of the starting and stop OFDM symbols for PDSCH and PUSCH.

Proposal 3-3: The bitfield in the DCI message indicating the starting and ending OFDM symbol within a slot is configured separately per CORESET

Furthermore, for UL and DL in some cases there would be a need to define in which slot the transmission of PUSCH or PDSCH should occur in. Such information could either be a separate bitfield or be jointly encoded with the starting and ending position. It is noted here however that to be able to support rather long periods of UL slot there would be a need for around 4 bits to support these cases. A similar need does not strictly exist for DL as in DL a DCI message can be provided in each DL slot so for DL the information could be joint coded with the location information within the slot or a single bit could be introduced to indicate scheduling in the next preceding slot.

Proposal 3-4

-   For PUSCH transmissions, an bitfield of up to 4 bits is introduced     in the DCI message to indicate which UL slot the PUSCH is     transmitted within -   For PDSCH, indication of which DL slot the PDSCH is transmitted is     either joint coded with the location information within the slot or     a single bit could be introduced to indicate scheduling in the next     preceding slot.

APPENDIX B

Some additional embodiments contemplated herein will now be described more fully with reference to FIGS. 8-14 . FIG. 8 is a schematic block diagram illustrating a virtualization environment 300 in which functions implemented by some embodiments may be virtualized. In the present context, virtualizing means creating virtual versions of apparatuses or devices which may include virtualizing hardware platforms, storage devices and networking resources. As used herein, virtualization can be applied to a node (e.g., a virtualized base station or a virtualized radio access node) or to a device (e.g., a UE, a wireless device or any other type of communication device) or components thereof and relates to an implementation in which at least a portion of the functionality is implemented as one or more virtual components (e.g., via one or more applications, components, functions, virtual machines or containers executing on one or more physical processing nodes in one or more networks).

In some embodiments, some or all of the functions described herein may be implemented as virtual components executed by one or more virtual machines implemented in one or more virtual environments 300 hosted by one or more of hardware nodes 330. Further, in embodiments in which the virtual node is not a radio access node or does not require radio connectivity (e.g., a core network node), then the network node may be entirely virtualized.

The functions may be implemented by one or more applications 320 (which may alternatively be called software instances, virtual appliances, network functions, virtual nodes, virtual network functions, etc.) operative to implement some of the features, functions, and/or benefits of some of the embodiments disclosed herein. Applications 320 are run in virtualization environment 300 which provides hardware 330 comprising processing circuitry 360 and memory 390. Memory 390 contains instructions 395 executable by processing circuitry 360 whereby application 320 is operative to provide one or more of the features, benefits, and/or functions disclosed herein.

Virtualization environment 300, comprises general-purpose or special-purpose network hardware devices 330 comprising a set of one or more processors or processing circuitry 360, which may be commercial off-the-shelf (COTS) processors, dedicated Application Specific Integrated Circuits (ASICs), or any other type of processing circuitry including digital or analog hardware components or special purpose processors. Each hardware device may comprise memory 390-1 which may be non-persistent memory for temporarily storing instructions 395 or software executed by processing circuitry 360. Each hardware device may comprise one or more network interface controllers (NICs) 370, also known as network interface cards, which include physical network interface 380. Each hardware device may also include non-transitory, persistent, machine-readable storage media 390-2 having stored therein software 395 and/or instructions executable by processing circuitry 360. Software 395 may include any type of software including software for instantiating one or more virtualization layers 350 (also referred to as hypervisors), software to execute virtual machines 340 as well as software allowing it to execute functions, features and/or benefits described in relation with some embodiments described herein.

Virtual machines 340, comprise virtual processing, virtual memory, virtual networking or interface and virtual storage, and may be run by a corresponding virtualization layer 350 or hypervisor. Different embodiments of the instance of virtual appliance 320 may be implemented on one or more of virtual machines 340, and the implementations may be made in different ways.

During operation, processing circuitry 360 executes software 395 to instantiate the hypervisor or virtualization layer 350, which may sometimes be referred to as a virtual machine monitor (VMM). Virtualization layer 350 may present a virtual operating platform that appears like networking hardware to virtual machine 340.

As shown in FIG. 8 , hardware 330 may be a standalone network node with generic or specific components. Hardware 330 may comprise antenna 3225 and may implement some functions via virtualization. Alternatively, hardware 330 may be part of a larger cluster of hardware (e.g., such as in a data center or customer premise equipment (CPE)) where many hardware nodes work together and are managed via management and orchestration (MANO) 3100, which, among others, oversees lifecycle management of applications 320.

Virtualization of the hardware is in some contexts referred to as network function virtualization (NFV). NFV may be used to consolidate many network equipment types onto industry standard high volume server hardware, physical switches, and physical storage, which can be located in data centers, and customer premise equipment.

In the context of NFV, virtual machine 340 may be a software implementation of a physical machine that runs programs as if they were executing on a physical, non-virtualized machine. Each of virtual machines 340, and that part of hardware 330 that executes that virtual machine, be it hardware dedicated to that virtual machine and/or hardware shared by that virtual machine with others of the virtual machines 340, forms a separate virtual network elements (VNE).

Still in the context of NFV, Virtual Network Function (VNF) is responsible for handling specific network functions that run in one or more virtual machines 340 on top of hardware networking infrastructure 330 and corresponds to application 320 in FIG. 8 .

In some embodiments, one or more radio units 3200 that each include one or more transmitters 3220 and one or more receivers 3210 may be coupled to one or more antennas 3225. Radio units 3200 may communicate directly with hardware nodes 330 via one or more appropriate network interfaces and may be used in combination with the virtual components to provide a virtual node with radio capabilities, such as a radio access node or a base station.

In some embodiments, some signalling can be effected with the use of control system 3230 which may alternatively be used for communication between the hardware nodes 330 and radio units 3200.

With reference to FIG. 9 , in accordance with an embodiment, a communication system includes telecommunication network 410, such as a 3GPP-type cellular network, which comprises access network 411, such as a radio access network, and core network 414. Access network 411 comprises a plurality of base stations 412 a, 412 b, 412 c, such as NBs, eNBs, gNBs or other types of wireless access points, each defining a corresponding coverage area 413 a, 413 b, 413 c. Each base station 412 a, 412 b, 412 c is connectable to core network 414 over a wired or wireless connection 415. A first UE 491 located in coverage area 413 c is configured to wirelessly connect to, or be paged by, the corresponding base station 412 c. A second UE 492 in coverage area 413 a is wirelessly connectable to the corresponding base station 412 a. While a plurality of UEs 491, 492 are illustrated in this example, the disclosed embodiments are equally applicable to a situation where a sole UE is in the coverage area or where a sole UE is connecting to the corresponding base station 412.

Telecommunication network 410 is itself connected to host computer 430, which may be embodied in the hardware and/or software of a standalone server, a cloud-implemented server, a distributed server or as processing resources in a server farm. Host computer 430 may be under the ownership or control of a service provider, or may be operated by the service provider or on behalf of the service provider. Connections 421 and 422 between telecommunication network 410 and host computer 430 may extend directly from core network 414 to host computer 430 or may go via an optional intermediate network 420. Intermediate network 420 may be one of, or a combination of more than one of, a public, private or hosted network; intermediate network 420, if any, may be a backbone network or the Internet; in particular, intermediate network 420 may comprise two or more sub-networks (not shown).

The communication system of FIG. 9 as a whole enables connectivity between the connected UEs 491, 492 and host computer 430. The connectivity may be described as an over-the-top (OTT) connection 450. Host computer 430 and the connected UEs 491, 492 are configured to communicate data and/or signaling via OTT connection 450, using access network 411, core network 414, any intermediate network 420 and possible further infrastructure (not shown) as intermediaries. OTT connection 450 may be transparent in the sense that the participating communication devices through which OTT connection 450 passes are unaware of routing of uplink and downlink communications. For example, base station 412 may not or need not be informed about the past routing of an incoming downlink communication with data originating from host computer 430 to be forwarded (e.g., handed over) to a connected UE 491. Similarly, base station 412 need not be aware of the future routing of an outgoing uplink communication originating from the UE 491 towards the host computer 430.

Example implementations, in accordance with an embodiment, of the UE, base station and host computer discussed in the preceding paragraphs will now be described with reference to FIG. 10 . In communication system 500, host computer 510 comprises hardware 515 including communication interface 516 configured to set up and maintain a wired or wireless connection with an interface of a different communication device of communication system 500. Host computer 510 further comprises processing circuitry 518, which may have storage and/or processing capabilities. In particular, processing circuitry 518 may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. Host computer 510 further comprises software 511, which is stored in or accessible by host computer 510 and executable by processing circuitry 518. Software 511 includes host application 512. Host application 512 may be operable to provide a service to a remote user, such as UE 530 connecting via OTT connection 550 terminating at UE 530 and host computer 510. In providing the service to the remote user, host application 512 may provide user data which is transmitted using OTT connection 550.

Communication system 500 further includes base station 520 provided in a telecommunication system and comprising hardware 525 enabling it to communicate with host computer 510 and with UE 530. Hardware 525 may include communication interface 526 for setting up and maintaining a wired or wireless connection with an interface of a different communication device of communication system 500, as well as radio interface 527 for setting up and maintaining at least wireless connection 570 with UE 530 located in a coverage area (not shown in FIG. 10 ) served by base station 520. Communication interface 526 may be configured to facilitate connection 560 to host computer 510. Connection 560 may be direct or it may pass through a core network (not shown in FIG. 10 ) of the telecommunication system and/or through one or more intermediate networks outside the telecommunication system. In the embodiment shown, hardware 525 of base station 520 further includes processing circuitry 528, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. Base station 520 further has software 521 stored internally or accessible via an external connection.

Communication system 500 further includes UE 530 already referred to. Its hardware 535 may include radio interface 537 configured to set up and maintain wireless connection 570 with a base station serving a coverage area in which UE 530 is currently located. Hardware 535 of UE 530 further includes processing circuitry 538, which may comprise one or more programmable processors, application-specific integrated circuits, field programmable gate arrays or combinations of these (not shown) adapted to execute instructions. UE 530 further comprises software 531, which is stored in or accessible by UE 530 and executable by processing circuitry 538. Software 531 includes client application 532. Client application 532 may be operable to provide a service to a human or non-human user via UE 530, with the support of host computer 510. In host computer 510, an executing host application 512 may communicate with the executing client application 532 via OTT connection 550 terminating at UE 530 and host computer 510. In providing the service to the user, client application 532 may receive request data from host application 512 and provide user data in response to the request data. OTT connection 550 may transfer both the request data and the user data. Client application 532 may interact with the user to generate the user data that it provides.

It is noted that host computer 510, base station 520 and UE 530 illustrated in FIG. 10 may be similar or identical to host computer 430, one of base stations 412 a, 412 b, 412 c and one of UEs 491, 492 of FIG. 9 , respectively. This is to say, the inner workings of these entities may be as shown in FIG. 10 and independently, the surrounding network topology may be that of FIG. 9 .

In FIG. 10 , OTT connection 550 has been drawn abstractly to illustrate the communication between host computer 510 and UE 530 via base station 520, without explicit reference to any intermediary devices and the precise routing of messages via these devices. Network infrastructure may determine the routing, which it may be configured to hide from UE 530 or from the service provider operating host computer 510, or both. While OTT connection 550 is active, the network infrastructure may further take decisions by which it dynamically changes the routing (e.g., on the basis of load balancing consideration or reconfiguration of the network).

Wireless connection 570 between UE 530 and base station 520 is in accordance with the teachings of the embodiments described throughout this disclosure. One or more of the various embodiments improve the performance of OTT services provided to UE 530 using OTT connection 550, in which wireless connection 570 forms the last segment. More precisely, the teachings of these embodiments may improve the data rate and latency, for example, by allowing for more flexible scheduling of time-domain resources, and thereby provide benefits such as reduced user waiting time.

A measurement procedure may be provided for the purpose of monitoring data rate, latency and other factors on which the one or more embodiments improve. There may further be an optional network functionality for reconfiguring OTT connection 550 between host computer 510 and UE 530, in response to variations in the measurement results. The measurement procedure and/or the network functionality for reconfiguring OTT connection 550 may be implemented in software 511 and hardware 515 of host computer 510 or in software 531 and hardware 535 of UE 530, or both. In embodiments, sensors (not shown) may be deployed in or in association with communication devices through which OTT connection 550 passes; the sensors may participate in the measurement procedure by supplying values of the monitored quantities exemplified above, or supplying values of other physical quantities from which software 511, 531 may compute or estimate the monitored quantities. The reconfiguring of OTT connection 550 may include message format, retransmission settings, preferred routing etc.; the reconfiguring need not affect base station 520, and it may be unknown or imperceptible to base station 520. Such procedures and functionalities may be known and practiced in the art. In certain embodiments, measurements may involve proprietary UE signaling facilitating host computer 510′s measurements of throughput, propagation times, latency and the like. The measurements may be implemented in that software 511 and 531 causes messages to be transmitted, in particular empty or ‘dummy’ messages, using OTT connection 550 while it monitors propagation times, errors etc.
